Networking features of Cisco Route

The networking features of Cisco Route are essential for a network to communicate normally. Cisco routers interconnect different networks to make more efficient use of network resources, it brings great convenience to your life and work.

I. Network isolation 1. With the development of the network, security has begun to attract people's attention. To improve network security, we need routers to achieve network interconnection with certain isolation capabilities, cisco access control technology is a simple and practical network isolation technology. It defines the access control list to filter and control packet forwarding, only packets permitted in the access control list can be forwarded through the vro. 2. the access control list currently used in routers can be used to control the access to packets based on MAC addresses, protocol types, network addresses, and other methods to achieve network isolation, cisco routers also provide content-based context-related access control for packets. Ii. Network Interconnection 1. the position and role of a Cisco router in the network determine that it must be able to interconnect multiple different networks, you can select the corresponding routing module and port based on the network link and Protocol connected to the router. 2. Routing Protocol: Because different types of networks may use different routing protocols, Cisco routers have the ability to support multiple routing protocols, in order to achieve correct routing and forwarding of packets between different networks.
3. Address ing: This function maps network-layer addresses and physical addresses of network devices. For example, the ing between IP addresses and MAC addresses is an important basis for routers to send protocol packets. 4. protocol conversion: This is a required function of a multi-protocol router. The router must implement mutual conversion between different network layer protocols. Www.2cto.com 5. Grouping and restructuring: Because vrouters connect to different types of networks, the MTU rules for these different types of networks are different, and vrouters need to group and reorganize packets. Iii. Address Translation 1. The Cisco router has the NAT Function. The network address translation function requires the LAN to use the reserved IP address, while the WAN port in the router uses the registered IP address. 2. When a computer in the LAN accesses an external computer, the IP address in the packet is converted to a registered IP address, and the external computer sends a message to the internal computer, also, the registered IP address is converted to an internal IP address.
4. Traffic Control because routers are usually used to connect the LAN to the WAN, when there is a large amount of data communication between the LAN and the WAN, the router usually becomes the bottleneck in the entire data communication, therefore, vrouters are required to have strong traffic control capabilities. On the one hand, when selecting a vro, we should consider the packet forwarding speed and buffer space of the vro as much as possible. At the same time, we should select an Optimized Routing Algorithm, server Load balancer technology is used to effectively control congestion. A vro is a key device in a networking environment and plays a key role. A network without a vro is incomplete. A Cisco vro will be a good helper for your daily work. This article is from
